Honestly, I have never seen a boosted vehicle rev higher than it's N/A counterpart...

http://www.gmpowertrain.com/VehicleE...nProducts.aspx They way I perceive it is that the LF3 has even larger valves than the LFX... But idk. Having not known the LFX valve sizes before, and reading about the LARGE LF3 valves, I thought it was something special... |

I just had it up, I'll see if I can find it again. The LLT valves are supposedly like 36.96mm while the LFX is stated to be 38.3mm, IIRC
And I admit, I was excited too. I too thought the LF3 would have larger intake and / or exhaust valves, which would be a huge bolt on mod for LFX guys.

Numbers wise, I don't see very much that's different between the LF3 and the LFX in this tech document, even though I know there are several changes. |

Hopefully you're on to something with the cams, if nothing else. Hopefully that would be a worthwhile mod... Hopefully.

Thanks for the info on the rods! I'm happy that the crank journal is the same size. I would love to run the new rods and pistons once I find out a 100% fitment.

No problem. It looks like they rods would be a direct swap if they were the same length. Same width, pin size, and journal size as the LFX rods. I bet the pistons will also work. I don't see anything different about the head valve angles. Unfortunately I don't have a part number or prices on pistons or rods yet.

I don't know if it's been stated yet, but it looks like the heads are different in respect to the throttle body location, so you'd probably need an LF3 head conversion to use the intake manifold... and the throttle bodies need to be checked to see if they are the same or different.

Again, theory. No one will know until someone tries it. I would imagine the throttle bodies themselves are at the very least, a different casting. I'm hoping they use similar electronics that can work with the LFX's current TB controls. I'll start slowly buying some of the key LF3 pieces once my LFX test motor shows up and confirm fitment as pieces show up. Last edited by Jason@JacFab; 03-11-2014 at 12:03 PM. |

I see what you're saying now. Hopefully you're right... LF3 manifold conversion (of course, with a custom intake at that point, lest you run the turbos) would be a decent upgrade.

I figure the pistons would work. The next battle is the LF3 heads and if they are needed with the pistons or not. Then of course there is shaking the ol' money tree.
